Okay, tried the test this evening, i used a nail. I brought them all in the barn and tied them, so no wind could move the nail, and just to be sure, i still infront of the way the wind would have blown incase any got in. Just for good meausres, i also just held the nail on the string out (not over a horse) just to make sure i was holding it steady and for atleast a minute no movement so i was very steady. Here are the results i got..
Candy - No movement of the nail = Open (Which is CORRECT as i had her palpated last week, so totally correct on her)
Dream - Very prominent circle, tested her two times and both resulted in strong circles. Took about 10 seconds or so, but a very strong circle. FILLY
Benita - Very strong circle, i tested her two times and both gave me very strong circles. FILLY
Angel - Straight back and forth line. COLT
